Letters-Patent No. 103,975, lated .Tune 7, 1870.

The Schedule referred to in these Lettera Patent and making part of the samev To all whom it mag/ concern lets, drills, countersinks, reamers," screw-drivers, &c.,

or alone, as a handle for chisels, keysaws,*les,a\v1s, 8vo., or as a bow drill-stock, all as hereinafter ex-` plan'ed;

Figures 1 andV 2 are respectively a longitudinal section and an end view of the body of my holder.

lFigures 3, 6, 7, 10, and A11, are views ot' tools used in lconnection with my handle.

Figures 4 and 5 are a side and an end view of the vremovable chuck, which also serves asa Ydrill-spindle.

Figure 8 -is'a side view of .myhandle with the chuck inserted, "and a saw secured therein.

Figure 9 is a longitudinal section of my holder with va bitand conntersink attached, showing the arrangementfor boring holes ofa uniform depth, and countersinking thesame at one operation.

s The body A of my holder I construct'of metal, -.substantiallyin the form shown in figsfl, 8, and 9, pro- .viding it at one end with a square shank, a, and boring in from the opposite. end a longitudinalhole, l), which may extend nearly through the body',"and inserting `through the body a loose pin or screw, c, flattened upon one side, whichwhen in one position, comes flush with hole l), but, nhentnrned over, projects into said hole,as shown in gs. land 9.' I -then provide my various tools, such 'as bits, reamers, gimlets, and screwdrivers, with `shanks ofthe proper size tofit the hole b, and .with notches i in said shanks, as shown in figs. 7, 9, andll 10, and then-insert the one desired for use, and turn the lockingpin c,so as 'to lock into one of the notches, and thus secure the tool to the handle, as-shownin fig. 9.

Ihe bits I insert so that their ends will project a distance equal to the depth of the required hole, the head d thus serving as a stop to prevent the bit from penetrating too deep, this arrangement being especial- 'ly useful in boring sash and blinds, where many holes of a uniform depth 4are reqnired,'andwhere the ordi- -nary bitslare liable toypass accidentally through the bars, thus marrin g their appearance.

If it is desired to bore holes and conntersink them, the head d is removed and a tubular countersink c slipped over the bit and screwed in place of the head, as in iig. 9, so as to come into operation when the bit has reached the desired depth, andthus the holes may be bored and countersunk simultaneously.

' When very' small bitsare used, whose shanks are of less diameter than the holev b, and itis required to countersink the holes made by them,.I use a countersink, c', iig. 3, made tapering andslotted longitudinally, so that, by screwing it into the end ofthe body, it may be compressed around the bit, so as to hold the same rigidly in place. v

-In addition to the body A I provide a chuck or spindle, B, consisting of a stem, e, and head f,the formcrfbeing provided with a notch whereby it may be secured within the body A, and the latter having .-a longitudinal hole, h,.a't the center, andbeing split longitudinally, and provided with a screw, g, whereby vthe halves may be compressed uponany `object placed between them..` v

.When it is desired to use awls, drills, liles, &c., the chuck B is secured within the 'body orhandle A, andV then the ends of the toolsinsertedin hole h of head j', and thepsc'rew g turned to compress the head upon them; but,'when saws and similar flat tools are' to be V used,.they are provided on opposite sides with studs' s, and with a hole through the end, as in fig. 6, and, the screw g being removed, they are inserted between the jaws of the head, and the screw y replaced, so asv to pass through the hole in the-tool, asshownin 655.8.

When my holder is to be used asa bowV drill-stock I drop into the hole ba hardened steel block, w, having a depression in its frontend, to serve as a bearing for the chuck orspindle, and then insertthe chuck securethc' drill in `its front end, and pass the bowstrirgfaround the head j, when the device will operate with as much' ease and facilityas a stock constructed for the especial'purpose.

It is, of course, obvious, that a bit-stock or handle ,is only used in connection with my device when using tools which require to be rotated, the holder alone serving asa handle vfor'iiles, saws, and other tools, which receive a reciprocating motion.

In selling` my improved device, the .intention is to provide the tool-holder-with a full set of small tools adapted to be'nsed with it, and fit the whole in a suitable case, and thus sell the whole together in sets, thereby furnishing a/complcte kit of small tools for the use of mechanics and others having use for them.

Havingthus .described my invention,

What I desire to secure by Letters Patent, is-

v1. The tool-holder A, provided with the removable head d, and locking-pin vc, constructed substantiall y as described.-

2. In combination with the tool-holder A, vthe conn-v tersink c, when constructed and arranged to' operate substantially as and for the purpose set forth.

3. The supplemental tool-holder or chuck B, having the stem c, and the split and recessed head f for holding drills, saws, files, and similar tools, and adapted to be used in combination with the holder A, snbstan tially as described.

4. The combinationl of the holder A, chuck B, and socket-pin w, constructed and arranged to operate as described.
